中文摘要：
预制装配式结构是未来建筑结构发展趋势，但是其整体抗震性能是装配式结构的薄弱环节。因此，将作者提出的剪切型软钢阻尼器设置于实际预制装配式钢筋混凝土高层剪力墙结构的连梁中部，以此提高整体结构抗震性能。该文基于ABAQUS有限元软件平台，提出一种可以有效模拟该软钢阻尼器剪切性能的连接单元，将其应用于该装配整体式剪力墙结构中，进行有限元建模和弹塑性时程分析，通过对比减震前后结构的相关地震反应，分析结构在罕遇地震作用下的减震效果。分析结果表明，设置阻尼器的减震结构，损伤连梁的数量明显减少，连梁阻尼器具有良好的耗能性能，层间位移角、结构损伤、基底反力均有所有减小。因此，采用这种软钢阻尼器可以提高装配整体式剪力墙结构的整体抗震性能。
英文摘要：
Prefabricated structure is promising in future. However, its overall seismic performance is unsatisfacto-ry. In this paper, the author put forward a mild steel damper, which was installed in the coupling beam of a practi-cal structure, aiming at improving its seismic performance. Based on ABAQUS software, this paper proposed a linkelement which can simulate the shear behavior of the damper effectively. Then, it was applied to the high-rise pre-fabricated shear wall structure subjected to seismic excitations.Through FEM modeling and nonlinear time-historyanalysis, seismic responses were analyzed and compared under rare earthquakes. The results show that the numberof damaged coupling beams decreases dramatically, and the damper has good performance of seismic migration. Inaddition, inter-story drift angle, reaction force and structuraldamagebecome smaller compared to the structurewithout damper. In the end, the overall seismic performance of the prefabricated shear wall structure is improvedwith the aid of proposed steel damper.
